i have working dump but i have incorrect coding and i cant change it with VCDS :/

[Pyromaniak]

I think this dump is unlocked like my dump, but is from another car.

[Darcar]

Its from octavia
but where in eeprom is write the coding value ?

[Pyromaniak]

how do you read and write eeprom? you soldering eeprom? maybe is problem here

i think my file is 100% corect

i think my file is 100% corect

Always desolder eeprom and use xprog 5.5.1 :/

[Pyromaniak]

I think, if start with octavia file, must start with my file... bad eeprom or bad soldering


What you mean guys?

[Darcar]
